The "active amygdala = no empathy" point does not jibe with my lay understanding of the physical phenomenon of empathy. That's the only one that I don't believe models our physiology in a useful way. The rest match up with some of the stuff I've read/watched. Watch some videos by Robert Sapolsky on YouTube. He's a neurostuff prof at Stanford. Good presentations. There's "Why Zebras Don't Get Ulcers" [link] Also an actual academic lecture on the Limbic System which contextualizes & clarifies some of the other assertions in the OP blog post. ▶ this video There are more but hopefully YouTube's algorithm helps you out there. The Stanford lecture series is very interesting though Sapolsky doesn't deliver all the lectures. edit: The only plausible, good faith explanation of the amygdala-empathy claim I can think of is that there are facial recognition studies designed to activate the amygdala [link] that showed some correlation between anxiety levels and ACC-amygdala connectivity. The ACC, or anterior cingulate cortex, is held to be responsible for empathy. So it may be an interpretation of that knowledge the author is talking about. I know that facial recognition tests are used for evaluation of empathy, sexual attraction and so on. This is probably the kernel of accuracy in the claim. Or there may be other science on the topic that reaches a conclusion closer to what the author said. The linked study is extremely interesting read.
